The U.S. Department of Energy (DOE) is continuously updating energy conservation standards and test procedures for refrigeration and air conditioning equipment. The expected results of these amendments is that consumers save money on their utility bills and reduce carbon dioxide emissions.

This is possible thanks to high efficiency technologies already available in the market that are constantly being improved. This paper presents the last energy conservation standards for commercial refrigeration equipment, with the purpose of facilitating to stakeholders the understanding of the regulation and how it should be applied.
